Edward Snowden has written an extensive open letter to the people of Brazil to discuss his findings and ultimately seek asylum.

In a broad letter published Tuesday by Brazil newspaper Folha de Sao Paulo, Snowden asks Brazil for the second time to grant him asylum. To make his case, for former NSA contractor said that his “act of conscience” prompted the US to make him “stateless.”

“The price for my speech was my passport, but I would pay it again: I will not be the one to ignore criminality for the sake of political comfort,” he wrote. “I would rather be without a state than without a voice.”

Snowden has received asylum offers from several South American countries, including Nicaragua, Bolivia, and Venezuela. He has petitioned Brazil to grant him asylum previously, but has so far been unable to obtain it. His latest overture centers on a singular idea: attempt to show the ways the NSA is allegedly spying on Brazil’s citizens.
